We have Icinga1 and Icinga2 as our monitoring system.

Icinga1: It is a fork of Nagios Icinga2: In this nagios is re-written from scratch

For Installation of Icinga1 on Ubuntu 14.04, refer to this link, it is explained over here.

Here Is the step by step procedure for installing Icinga2

**Step 1: **Add repository and install icinga2 on both host and monitoring server

#add-apt-repository ppa:formorer/icinga
#apt-get update
#apt-get install icinga2

**Step 2: **Install MySQL database on Monitoring Server

#apt-get install mysql-server mysql-client

**Step 3: **Install Icinga2 Database

#apt-get install icinga2-ido-mysql

**Step 4: ** Login to Mysql Database

#mysql -u root -p

**Step 5: **Now create a database named 'icinga' and assign privileges to it. For that run following in mysql shell

CREATE DATABASE icinga;
GRANT SELECT, INSERT, UPDATE, DELETE, DROP, CREATE VIEW, INDEX, EXECUTE ON icinga.* TO 'icinga'@'localhost' IDENTIFIED BY 'icinga';
quit

**Step 6: **Enable livestatus feature

#icinga2 feature enable livestatus

**Step 7: **Restart Icinga

#   service icinga2 restart

**Step 8: **Assign User mode usermod -a -G nagios www-data

**Step 9: **Enable some features

#icinga2 feature enable compatlog
#icinga2 feature enable ido-mysql
#icinga2 feature enable command
#service icinga2 restart

For installing Web View, go through this process **Step 1: ** Install Git

#apt-get install git

**Step 2: ** Clone web view repository

#git clone git://git.icinga.org/icingaweb2.git

**Step 3: **Move cloned directory to /usr/share/icingaweb

#mv ../icingaweb2 /usr/share/icingaweb

**Step 4: **Navigate to /usr/share/icingaweb

#cd /usr/share/icingaweb

**Step 5: **Install Lamp Server

#apt-get install tasksel
#apt-get install lamp-server

**Step 6: **Configure apache with icinga

./bin/icingacli setup config webserver apache --document-root /usr/share/icingaweb/public

**Step 8: **Above command will generate a apache configuration code, copy the code generated code and add this directory to be listen at port 80 in configuration file. You can make a new configuration file and activate that file using a2ensites command or add the code to 000-default.conf file

**Step 9: **restart apache #a2enmod rewrite #service apache2 restart

**Step 10: **Create a directory in which icinga web will keep all of its authentication files

#mkdir /etc/icingaweb2

**Step 11: **Shange its permission to 777

#chmod 777 -R /etc/icingaweb

**Step 12: **Now open your favorite Browser and navigate to localhost/icingaweb2/setup its asking for setup token, generate it by follwing command.

#su www-data --shell=/bin/bash -c "mkdir -m 2770 /etc/icingaweb2; head -c 12 /dev/urandom | base64 | tee /etc/icingaweb2/setup.token; chmod 0660 /etc/icingaweb2/setup.token;";

You are done, you are ready for monitoring. Just resolve some packages dependencies of php5 and setup your monitoring server

  • Thanks for your reply...Which should I use Icinga1 and Icinga2 ? Also Please provide me the steps to install on LINUX server not on Ubuntu...plz – Linux user Jan 15 '15 at 13:36
  • I will prefer icina2. Which LINUX flavor are you using? As only syntax are changed but procedure is same for any linux distribution. Even you can go through the Official Getting Started Link that I have provided at the end of aforementioned answer. – Lavish Jan 15 '15 at 13:40
  • What are the difference of Icinga1 and Icinga2 ? WE are using Centos...Please provide me the steps to install on Centos – Linux user Jan 15 '15 at 13:49
  • In a simple words Icinga1 is old one and Icinga2 in the latest version with Improved UX/UI. https://docs.icinga.org/icinga2/latest/doc/module/icinga2/ . This link will provide the answer of your all questions. Go through offical documentation once. And as I have mentioned earlier the process is same for setting up Icinga on any Linux Flavor, the only difference is of packages, which you can find in mentioned link. – Lavish Jan 15 '15 at 13:58
